The envelope

See how structural insulated panels change airtightness, whole-wall insulation, and tested structural performance.
Why How You Build Matters
A practical, research-backed guide to the envelope, air, energy, materials, and Colorado-specific details that shape a home's next forty years.
The finishes matter. The parts behind them matter longer.
A forever home is experienced for decades after the final walkthrough. Kiefer Built starts with the questions that shape those years: how the shell controls air and moisture, what the mechanical system must overcome, and how the structure responds to Colorado weather. We educate first so buyers can decide where better performance is worth the up-front investment.
Measured performance
Energy Efficiency
Move beyond projections to a full year of Oak Ridge data, national DOE results, and a Colorado homeowner case study.
Health & comfort
Indoor Air Quality
Learn why a leaky home and an airtight home without planned ventilation both miss half of the indoor-air problem.
Hail, wildfire, snow & wind
Built for Colorado
Connect material and structural decisions to the weather risks Northern Colorado homes actually face.
The details
Quality & Craftsmanship
See how owner accountability and moisture-aware material coordination protect the work long after move-in.
The long view
Cost Of Ownership
Compare the lowest construction price with the energy, weather exposure, and repair costs that continue after closing.

- U.S. Environmental Protection Agency, The Inside Story: A Guide to Indoor Air Quality, and EPA Report on the Environment. Indoor air can be two to five times more polluted than outdoor air; people spend roughly 90% of their time indoors; energy-efficient construction without sufficient ventilation can worsen indoor air quality.
- U.S. Department of Energy, Zero Energy Ready Home (ZERH) Program, National Program Requirements. DOE-certified ZERH homes — over 12,000 nationwide — are typically 40–50% more energy-efficient than a typical new home, and must meet EPA Indoor airPLUS indoor-air-quality requirements as a condition of certification.
- Rocky Mountain Insurance Information Association and Colorado Division of Insurance, public hail-loss reporting. Colorado ranks second nationally in hail insurance claims; hail has been the leading driver of the state's insured losses in eight of the past eleven years; the May 2017 Denver-metro hailstorm caused an estimated $2.3 billion in damage.
